Sun, air and ... circumnavigation of the world without fuel? Yes, it is possible!

Environmentally friendly long-distance air travel becomes a reality, if, of course, you are not in a hurry. The Solar Airship One airship plans to complete a journey around the equator, about 40,000 km long, in 20 days without emitting harmful substances.

With a length of 151 meters, the upper surface of the airship will be covered with solar panels with a total area of about 4,800 square meters. During the day, solar panels will ensure the operation of the airship's electrical systems, as well as store energy for night time, turning water into hydrogen. At night, hydrogen will be used in fuel cells to keep the vehicle moving.

The airship's crew will consist of three people: former French astronaut and Air Force pilot Michel Tognini, plane crash survivor and acrobat pilot Doreen Burneton, and adventurer Bertrand Picard, who first circumnavigated the world in a hot air balloon in 1999 and was the pilot of Solar Impulse 2 on the first solar-powered round-the-world flight in 2015-16.

Although the average speed of the airship will be only about 83 km / h, it has a number of advantages. For example, it can take off and land almost anywhere without the need for a runway.

Some projects , such as AirYacht and Airlander, are considering using airships as a luxury vehicle, while others see them as the future of eco-friendly cargo transportation.

However, it is worth noting that despite the use of renewable energy, one key component of the airship is not renewable. Its rigid structure is filled with helium, which, leaking into the atmosphere, flies into space and cannot be restored. The Euro Airship team plans to start its round-the-world journey in 2026, mainly following the equator at an altitude of about 6,000 meters.
